Description

Technical Field

[0001] The utility model relates to underground pipeline construction equipment, in particular to a transportation device for large-diameter precast pipelines in a trunk tunnel type utility tunnel truss. Background Art

[0002] The space structure of the trunk tunnel type utility tunnel is long and narrow.

Due to the limited space of the maintenance passage and the pipeline length being greater than the truss spacing, transporting large-diameter pipelines into the truss system is a relatively difficult process. The existing pipeline transportation method is to use a tractor and a mobile trolley to transport from the hoisting hole along the maintenance passage to the installation position, and then use machinery such as a forklift and a chain block to cooperate to insert into the truss. The process is cumbersome, consuming a large amount of labor and machinery, and the installation efficiency is low. Summary of the Utility Model
